Hi all,

I have been using SMath Studio for several months, running as an AppImage on Linux Mint 21, without any problems. Recently, I upgraded to Linux Mint 22 and SMath Studio crashes when running. All errors are the following:

Restoring environment...

Any idea how I can fix this? Thanks.

Can you look if libgdiplus is installed?
Error messages are referring to that library.

Yes it is installed on my system

Can you look if mono package is working?
Maybe some libraries of new mint is not compatible with appimage.

Mono version does not work. I think that some libraries are not compatible with this SMath version...

Debian and debian based distros are always problematic with mono.
If you can make smath run with sudo, then there is a possible workaround.
Otherwise I'm sorry, it is debian (or ubuntu or mint)
